not sure if I completely understand your question or not but I use the so called "cheap" holley regs on the nitrous with no problems.
I set them flowing and they are dead headed and work perfect. After the nitrous is activated they go right to where they are suspose to be. A little pressure creap just before activation is not always a bad thing, especially with all the lines you have to fill in a direct port deal.

mine doesnt quite creep that high but I set it flowing and forget about it. Spraying what most guys consider a lot!

It allo depends on perference really. There has been numerous long threads on here about the ordeal and about pressure creep vs. bleed valves, etc.
I think the best thing I could tell you would be, if you have someone that helps with your tune ups and nitrous, do what they want you to do and let it ride. People have been sucessful doing it both ways.
I use SJohnson for my stuff and what he says, I do!

Thanks for the feedback, ran it Sat & everything worked as supposed to. When the kit comes on fuel pressure goes right to where it should.

thats the way I like it, but thats just me!
